I've decided to take out a HELOC and pay her with that rather than refinance. The interest rate on my loan is too good to consider refinancing and my bank offers HELOCs that allow you to make principal and interest payments during the draw period so I would immediately start paying down the principal. I ran the numbers and I would end up paying roughly the same if I refinanced, but I would be starting the mortgage over and I want the house paid off before I retire.
